Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a device for discharging soot dust adhering to an exhaust pipe of an engine of a construction vehicle or the like so as to prevent contamination around the engine from occurring.

[Conventional technology]

A muffler attached to the engine body of a construction vehicle,
Since the vibration system is different from the exhaust pipe attached to the engine cover, it is easily damaged if it is directly connected. Therefore, as shown in FIG. 3, a gap was provided between the exhaust port 5 of the muffler 1 and the inlet 6 of the exhaust pipe 3.

[Problems to be solved by the device]

Since there is a gap between the exhaust port 5 of the muffler 1 and the inlet 6 of the exhaust pipe 3, when rainwater enters from the outlet 11 of the exhaust pipe 3, the soot dust adhering to the inner wall 3 _i of the exhaust pipe 3 becomes muffler 1. There was a problem that it flowed down to the side and polluted around the muffler 1 and the engine 2.

This invention solves such a problem in an exhaust pipe of an engine of a construction vehicle, etc., and prevents muffler and engine-related pollution caused by rainwater and the like entering the exhaust pipe and flowing down dust adhered to the inner wall. It is an object of the present invention to provide an exhaust pipe soot and dust discharge device capable of performing the above.

[Means for solving the problem]

In this invention, in an exhaust equipment such as a construction vehicle in which a gap is provided between the muffler attached to the engine body and the exhaust pipe attached to the engine cover, a water collecting panel is provided annularly along the inner wall of the exhaust pipe to The above problem is solved by piping a drainage pipe inside the pipe and connecting the upper end to the water collecting plate, and the lower part of the drainage ring is a flexible pipe and the lower end is connected to the drainage hose of the muffler.

[Action]

When rainwater or the like enters the exhaust pipe, the soot dust adhering to the inner wall of the exhaust pipe flows down along the inner wall of the exhaust pipe. The soot that has flowed down is collected by the water collection board, and is discharged from the drain pipe connected to the water collection board through the drain hose of the muffler to the lower part of the vehicle body of the construction vehicle or the like.

〔Example〕

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows the configuration of an embodiment of the present invention. here,
The muffler 1 is attached to the main body of the engine 2, the exhaust pipe 3 is attached to the engine cover 4, and a gap is provided between the exhaust port 5 of the muffler 1 and the inlet 6 of the exhaust pipe 3. . A water collecting plate 7 is fixedly installed on the inner wall 3 _i of the exhaust pipe 3. As shown in FIG. 2, the water collecting board 7 has an annular shape, to which the upper end of the drainage pipe 8 is connected. A lower portion of the drainage pipe 8 is a flexible pipe, and a lower end of the drainage pipe 8 is connected to a drainage hose 9 of the muffler 1. In this way, since the drain pipe 8 is connected to the drain hose 9 of the muffler 1 from the water collection board 7 through the inside of the drain pipe 3, the pipe can be short and the lower portion is a flexible pipe. Connection work to the drain hose 9 can be easily performed. 10 is a radiator.

When rainwater or the like enters through the inlet 11 of the exhaust pipe 3, the exhaust pipe 3
Although it flows down along the inner wall 3 _i dust adhering to the inner wall 3 of the _i, flowing down the dust is collected in the collecting basin 7, drainage pipes 8
Since it is discharged to the lower part of the vehicle body of the construction vehicle through the drainage hose 9, contamination by the soot dust around the muffler 1 and the engine 2 is prevented.

[Effect of device]

According to this invention, even if rainwater or the like enters the exhaust pipe and the soot dust adhering to the inner wall flows down, the muffler and the surroundings of the engine are not polluted. Further, since the drainage pipe has a short pipe and the lower portion is a flexible pipe, there is an effect that the connection work to the drainage hose can be easily performed.
